I'm not sure if it makes any difference, but... mailman should resolve
Mailman is not a DNS server. It doesn't 'resolve' domains.
I have a contact.enterprise.com subdomain.
And I don't have any list.contact.enterprise.com.
Actually, even the name server at ns1.enterprise.com has no A or MX
records for either domain, contact.enterprise.com or
That raises the issue of how external mail even gets far enough to get
a "Recipient address rejected: User unknown in virtual mailbox table"
I mean, Mailman should resolve directly the contact.enterprise.com
I have a MX record in enterprise.com DNS server pointing to
Not that I can see?

And 'contact' machine is where the postfix/mailman is installed.
I still stuck on "User unknown in virtual mailbox table".
And I can't imagine why this error doesn't happen when I'm using an
account (even from another domain) hosted at the same
If I send mail to local_address at lists.contact.enterprise.com, there
MUST be an MX or an A record in DNS for lists.contact.enterprise.com,
or my MTA doesn't know where to attempt to deliver that mail. It
doesn't 'fall back' to contact.enterprise.com or enterprise.com; it
just gives up. All this has to work before the message will even get
to the server that Mailman is running on.
If the Mailman/Postfix server is contact.enterprise.com, you need an A
record for contact.enterprise.com and an MX record for
lists.contact.enterprise.com giving contact.enterprise.com as the
target. Otherwise, the mail will never get to your server.
Alternatively, you can have just an A record for
lists.contact.enterprise.com giving the IP address of the server.
You don't appear to have any of these DNS records.
